Key Terms

per- and polyfluoroalkyl substances, pfas, granular activated carbon

3 terms

per- and polyfluoroalkyl substances medical

"system designed to remove per- and polyfluoroalkyl substances or PFAS."

Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals known for resisting water, grease and heat, used historically in products like nonstick cookware, firefighting foams and stain-resistant fabrics. They matter to investors because PFAS can persist in the environment and people, prompting strict regulations, cleanup costs, product liability and shifting consumer demand — like a hidden leak that can suddenly require expensive repairs and change a company’s future cash flow and reputation.

pfas medical

"designed to remove per- and polyfluoroalkyl substances or PFAS."

PFAS are a group of human-made chemicals used in many everyday products, such as non-stick cookware, water-repellent clothing, and food packaging, because they resist heat, water, and grease. They are often called "forever chemicals" because they do not break down easily in the environment or the human body, potentially leading to health concerns. For investors, the presence of PFAS-related risks can impact companies’ reputations, legal liabilities, and future costs.

granular activated carbon technical

"includes the granular activated carbon or GAC system and also supports infrastructure"

Granular activated carbon is a highly porous, sand-like form of carbon that acts like a microscopic sponge to trap impurities, chemicals, and odors from water and air. Investors pay attention because its demand and price reflect spending on clean-water and air-treatment projects, regulatory cleanup requirements, and certain industrial or energy applications; changes in supply, technology or rules can affect revenues and capital needs for companies that make or use it.

CHARLESTOWN, Ind., Jan. 29, 2026 /PRNewswire/ -- Indiana American Water held a ribbon cutting ceremony today at its Charlestown water treatment plant. The company announced that the facility is now operating Indiana's first drinking water treatment system designed to remove per- and polyfluoroalkyl substances or PFAS. The nearly $6 million system investment, which went online last month, marks another major milestone in protecting public health and improving water quality for the community.

"We are proud to partner with Indiana American Water on this important project," said Treva Hodges, Mayor of the City of Charlestown. "Access to high-quality drinking water is essential for the health and well-being of our community, and this new treatment system shows a forward-thinking approach to community safety. Continued improvements to our water system have helped Charlestown achieve a higher quality of life and have spurred community growth, making our city an even more attractive place to live and invest."

According to the Indiana Department of Environmental Management (IDEM), this is the first PFAS treatment installation in a public water system in the state. PFAS are a group of manufactured chemicals that have been used for decades in industrial and consumer products and are known for their persistence in the environment and potential health risks.

To celebrate this milestone, an official ribbon-cutting ceremony was held on January 29, 2026, with local officials, community leaders, and Indiana American Water representatives in attendance.

"This investment underscores our continued commitment to delivering safe, clean, and reliable water to our customers," said Barry Suits, President of Indiana American Water. "By proactively addressing PFAS, we are leading the way in Indiana and setting the standard for future water quality improvements across the state. This project also provided us with an opportunity to gain valuable experience in adding PFAS treatment, which will guide and inform similar upgrades at other systems as we make these investments over the coming years." 

This investment builds on Indiana American Water's commitment to Charlestown, following the commissioning of the $16 million water treatment plant in 2022. The PFAS upgrade is supported by Indiana's State Revolving Fund Loan Program, which allows the company to finance the project at a lower cost than traditional loans. This additional investment includes the granular activated carbon or GAC system and also supports infrastructure such as pumps, piping, electrical systems, and controls. Charlestown was selected for this enhancement because the original plant was designed to accommodate future improvements, making it an ideal location for this advanced treatment technology.

The Charlestown facility serves approximately 3,000 customers, or about 8,000 residents and businesses, with four percent of its daily production sold to neighboring Marysville-Otisco Nabb Water Corporation. Indiana American Water's Water Quality Reports, published annually, confirm that all Indiana American Water systems meet or surpass federal and state drinking water standards.

Future PFAS Investments in Indiana

Indiana American Water is committed to expanding PFAS treatment capabilities across other service areas. Plans are underway for similar upgrades to its water systems in Terre Haute, Johnson County and other communities as funding becomes available. These investments are part of a broader strategy to ensure compliance with evolving water quality regulations and to safeguard public health for generations to come.
